In the early 1960s, Richard Feynman was quoted as saying that Earth's center should be a day or two younger than its surface. 50 years later, scientists re-did the math.

New research suggests that Venus’ patterned crust might currently be more active than we thought! Astrophysicists have also modeled the orbits of mysterious objects between Jupiter and Neptune, and found that they could have come from...

It takes light a zippy 8 minutes to reach Earth from the surface of the Sun. But how long does it take that same light to travel from the Sun's core to its surface? Oddly enough, the answer is many thousands of years. Sten Odenwald...

All the stars in a spiral galaxy rotate around a center -- but to astronomers, the speed that each star travels wasn't making sense. Why didn't stars slow down toward the edges as expected? Don Lincoln explains how a mysterious force...

Finding a red nugget galaxy is like discovering a time capsule from the early universe.

After months of travel, you've arrived at Duonia, home to the famous temple that's the destination of your pilgrimage. The walk from the welcome center to the temple isn't a long one ... but there's a problem. Can you outsmart the city's...

We may soon have a direct image of a black hole, and we have the first detection of an atmosphere on an Earth-sized exoplanet!

Meet one of the newest celestial bodies to be discovered: rogue planets, worlds that hurtle around the galaxy without any parent star. Caitlin Hofmeister explains how we found them, and where we think they might have come from.

There are some captivating things when you look up at the night sky, but our location in the Milky Way may be fogging up our view.

SciShow explains the science of detecting exoplanets -- planets in orbit around distant stars -- and how a new observatory being built in California may open up whole new worlds to us, literally!

Thanks to @AstroKatie () for the collaboration!





This video is about the cosmic distance scale and how we see objects farther away in space (ie at...

A new model has been able to predict solar flares with up to about 20 hours of warning, and our galaxy is farting blobs of cold gas inside the Fermi Bubbles!

Astronomers are learning just how big early stars might have been, and how their deaths have shaped the universe. Some may have even been so massive that they skipped the whole star phase and collapsed straight into black holes!

American designer Chris Bangle explains his philosophy that car design is an art form in its own right, with an entertaining -- and ultimately moving -- account of the BMW Group's Deep Blue project, intended to create the SUV of the future.

It's leap year time... so what are years, anyway? And what do they have to do with the supermassive black hole in the core of the milky way?

Part of being very far away from the rest of the universe is that the signals are very faint, so sometimes you need a nice, quiet spot to listen from.

How to Find an Exoplanet

In the spectacular large-scale projects he's famous for (such as "Waterfalls" in New York harbor), Olafur Eliasson creates art from a palette of space, distance, color and light. This idea-packed talk begins with an experiment in the...

In this edition of IDTIMWYTIM, Hank explains why the common understanding of "equinox" is wrong, what the equinox actually is, and then rages a little against astronomers and their stupid confusing Latin terms.

One of the most fundamental ideas in physics is that the disorder of the universe, also known as entropy, is constantly increasing. But, life’s inherent chemical makeup has been hacking the disorder of the universe for billions of years!

From asteroid spaceships, to exploring ice volcanoes, let's look at a few of the NIAC's recently approved Phase I projects!

One of Saturn's moons looks a lot like an infamous planet-destroying battle station from science fiction, but astronomers have some very real theories about the complex crater that gives Mimas its unique feature.

Join the Cossack soldier Stepan as he tries to keep order in the battalion and help his people regain their independence. -- The year is 1676, and a treaty has officially ended hostilities between the Polish-Lithuanian Commonwealth...

Hollywood can be pretty negligent about physics and astronomy, even in really good movies, but there are a few specific misconceptions that pop up again and again.
